RUBBER MIXTURE WITH IMPROVED ROLLING RESISTANCE

摘要

Rubber mixture (I) comprises: at least one completely or partially functionalized styrene butadiene rubber (60-100 parts per hundred parts of rubber (phr)); at least one other polar or non-polar rubber (0-40 phr); at least one carbon black (0.01-20 phr); at least a silicic acid (1-300 phr); at least one mercaptosilane (0.1 to 40 phr); at least one substance-A (0.1-10 phr), that contains partially passivating ligands that influence the reactivity of functional groups of the styrene butadiene rubber; and additives.
